The correct title of the book should be:
The Complete Works Friedrich Nietzsche, Vol XIV:
The Will to Power : An Attempted Transvaluation of All Values
The publisher is not 'The Will to Power'; that is the work in question, which, if I am not mistaken, continues in volume XV. The publisher information is probably the following:
London : T.N. Foulis, 1910-1014.

None of this is absolutely sure, since not all of the pertinent information is visible in the scan (which cuts off the left-hand side of the title page)
